$B \to K^* \ell^+ \ell^-$ as a probe of Universal Extra Dimensions

We study some rare B decays induced by $b \to s$ transition within the Standard Model and in the Appelquist-Cheng-Dobrescu model, which is a New Physics scenario with a single universal extra dimension. In particular, we discuss the dependence on the radius $R$ of the compactified extra-dimension of the branching ratio, the forward-backward asymmetry and the $K^*$ helicity distributions for the decay modes $B \to K^* \ell^+ \ell^-$, with $\ell^-=e^-,μ^-$, and the tau polarization asymmetries for the mode $B \to K^* τ^+ τ^-$.

Probing Universal Extra Dimensions through rare decays induced by $b \to s$ transition

A few $B_{d,s}$ and $Λ_b$ decays induced by $b \to s$ transition are studied in the Standard Model and in the framework of the Appelquist, Cheng and Dobrescu (ACD) model, which is a New Physics scenario where a single universal extra dimension is considered. In particular, we investigate the sensitivity of the observables to the radius $R$ of the compactified extra dimension.
